Choose a shampoo and conditioner that is specialized for color treated hairs, Tresemme is my favorite shampoo over all, Tresemme Color Revitalize Shampoo is specialized for color treated hair.
But I think the problem is not your shampoo,
Can you answer with a YES for one of the following:
>Do you think that the dye you used is not a good brand? (Cheapest isn't always a budget saver)
>Do exposure to sunlight a lot? (The sun Dry out any hair color, making it look dull and lifeless.)
>Do you swim a lot? (Chemicals in pools aren't color treated hair best friend.)
>Do you shower in hot water a lot?
Tip: When rinsing out dye, or washing your hair, use only cold water.
Your hair color will last longer.

John Frieda makes specific shampoo's and conditioners for different color treated hair. They have a range specifically dedicated to brunette's and to help with color fade. I use their blonde line and it works great. Highly recommend John Frieda :D1
